12` claims. (ci. 19-1z7) The invention relates to a gill -box with gill bars linked to endless chains and which can be turned with respect to the,` chains lby means of controlled cranks.

In conyentiona-l devices offthe kind here under consideration, thegill b ars are arranged in a swivel-like manner in order, tor utilize the space provided for the set of gill barsbetweeu the usually existing drawing cylinders as completelyas possible.. VIn such devices, the gill bars are controlled so thatl theirl AI'Ieedles orteeth arev substantially aftfright. angles tothe plane vof' the set of barswhere they enter and. leave the ber band, and, Vso that-they are sub? Si. Thebr'acketsS-fof the Eatented; J 1y 26' 196@ ice shaped differently iforl reasons 'to be explained l'ater.f

Means'- are providedfto keepthe needles oriented in' one basicfdirection throughoutr their entire path. Thisl direction correspondsto and is parallel with the position of use. In other words, all the needles on all the bars'are keptparall'elto eachother. For this purpose, cranks 10 stantially at right angles to4 the chains at the reversing points of the latter; In any position of the chains, the pointsv of the needles are outwardly directed so that they must beturned through, aratherlarge angleY prior to their entrance into and, after their withdrawal from the liber band. Consequently, the speedY of .the` chains is limited and. the chains must- 'be specially guided in order to pass the closely located drawing cylinders due to4 the greatv length, of theswivel` path. v y, TheA invention aimsto. avoid the mentioned drawback and to provide meansv whereby the needles, of the gill bars inthe straight portion oftheir path. will' be increased bars are held Vthroughout their entire path in a position v parallelv to their position of use.

.Another object of rthe invention is the provision of means. whereby a gill bar can be readily exchanged for anotherl one. y

vReferring now'to thejdrawings, the illustrated device comprisestwo. substantially similar gill bar sets or` assem blie`s,-1gener'ally designated by A and B, which are arranged one below the other( In both sets like reference charactersfare used? for similar parts, but those of the upper set Bfhaveia (")L added to the numeral. In, view of the similarity of the -parts except for features which will be specially explained, the, following description can and willi-ibs restricted mainly to the set Ait being understood that "thel saine description can be Iapplied to theA set B;

Each set"'compri ses two.V pairs of sprocket wheels of whichfthefwheels of a pair rotatable in'.Y spaced relation about thesarneaxisfaaredesignated 1 whereas the wheels ofapai'r"inthe'saineplane as the wheels 1, respectively, and rotatable about 'an laxis: b parallel tov anisy a are designated 2. Anrendless chain 3 is placed about one pair of sprocket' wheels 1 and'Z andv another endless chain 4 is-p'la'ced abouti the otherzpai'r oi wheels 1 and 2. The chains lare provided with outwardly projecting brackets are VsecuredV to thefpi'ns 6'by means indicatedv at 26; Each crank 10' has another outwardly directed p-in 1^-1 for controlling'theassociatedJ bar "8; Each pin` 11Y engages in brackets 12whiclr` aresimilar to the brackets 5` and` connected tofanotherj endless chain '13/ placed-about a` pai'r of sprocketwheels 114 and 25, as clearly' slruiawnv inv Figs;v 2A and13'. The chain '13 is, so staggered with respect to the', nains s and 4- thaw-harm s: with the needles 9m the reversing points of'theirv'chainsV 3f and 4 are'turned from a position in which they. run above into one'below 'the chains orviicevversa. As a' result, they bars Sfwith needles. 9 will' rotate in` relation to each other at the reversing points of their chains. Because of the outwardly projecting brackets 5 the spacing 18` between adjacent to the 'spacing 19 at the' reversing points as shown'in Eig `l1 Ihis provides clearancebetween yadjacent'bars wh hjwould'otherwisenot exist. l Y y Y the illustrated' embodiment needles 9'lare upwardly directedY andf'rieedlles 9 of', the upper set' B are Vdown-v wardly directed so as toenter, into the ber band 11 moving inthe direction o f the arrow c in Fig. l, in which thedrawingcylinders 15 and 16 are indicated' by dash and dot lines. It will4 also be noted that cha-ins 3i, 4 are l staggered with respect 'to the chains 3', d" sov that at their adjacent sides each needle 9. engages in the fiber band in the space betweentwo adjacent needles Si.

The cranks lil are, keyedgt'o, ther gillharsSf and.' are journalled within the brackets Anotherk pin 1'11 of crank 10 is journ'alledi Within thebrackets 1'2. Thus whenever the axes of` the pins 1'1 are below the axes of the gill bars 8, thenfeedles 9 wiljlvjpoint up.

Means. are preferably providedl 'to 'facilitate thek 'as sembling and removing of each individual gill bar. For this pnrpose, ini the illustrated embodiment as clearly shown in Eig,1'4,the. headl' 0f piu 6"and' the coz-Ordinate recess VV21" of' the end of a gill bar '8' are of va' square cross-V section.

chain 3 have pins mountedv 8' it is only necessary to push pin 7 back against the restraint of spring 22' so that the opposite bar end clears the pin head 20 whereupon the bar can be tilted about the spherical h'ead 23', as shown in Fig; 4, and in this position, stripped from that head. f

It will be apparent to those skilled in the art4 that alterations and modications of the structure shown and herenbefore described can be made without departure from the essence and spirit of the invention which for this reason shall not be limited but by the scope of the appended claims.
